Is There A Choke You do with your legs?

I'm just curious if there is a choke you do with your legs and no it's not a triangle.
When I was in no-gi grappling there was one leg choke I'd use that I improvised completely for the purpose of tapping a guy who seemed like he could resist my arm bars on pure strength no matter how well I thought I applied them.

Basically what I'd do is I'd go for an armbar and when he started resisting I'd slip my foot behind his head so my knee would be at his neck basically creating a hinge around his neck, then I'd apply pressure by simply leaning more on that leg then the other and he'd have to tap.
If he tried to roll out I'd just sit up and grab one of his ankles with my opposite arm so he couldn't wriggle away too much.

Now as far as I know this move (I don't know what it's called) isn't used in grappling comps so I'm wondering what higher belts do to make this move kind of useless

I don't know if I'm picturing it right, but it sounds like an unsecured scissors choke.

If your knee is besides his head above his shoulder that is the furthest away from you, then you are crushing his trachea, what is illegal in competitions, can't be trained safe at all and can even kill your trainingpartner.

In what competition is it illegal to crush the trachea? It's perfectly legal in, for example, Judo, BJJ, ADCC, MMA. The high-elbow guillotine is a trachea crush first and foremost.

Sounds a bit like you're doing a mounted gogoplata, maybe? Like so:
It's been used in MMA at the top level. It's a less common move, and a lot of people see it as gimmicky, but it certainly works.

Sport SAMBO ;-p

Just kidding, but what he describes doesn't sound like a mounted gogoplata to me.
More like a scissor type of choke with the neck stuck between the calf and the backside of the upperleg.

That would be considered as an unsecured position (mantra: position before submission) and here in the BeNeLux at white belt division in BJJ, the ref would stop the fight, give you a warning and continue the fight from standing position again.

Remember that the OP is studying Goju-Ryu Karate for one year only, at a school where the instructor also according to the OP has a brown belt in BJJ and is experienced in MT, but is teaching Goju.
Which makes the OP an absolute beginner in grappling.

I haven't started Jutsu from my dojo yet. I took 4-5 months of no gi grappling in University which is what I'm talking about. Also I wrestled for a year and we were a practice every day team for 1-3 hours a practice.

anyways the choke is like the one in the picture but instead of being infront of his neck the shin is behind his neck so there is leg both on the top and bottom of his neck.

I don't know if it could be done from mount i usually did it from arm bar attempt
